摘要:
One‐dimensional scattering of acoustic waves by the thermal field produced by a sinusoidal spatial distribution of heat sources in a perfect gas is examined analytically. The scattered field is found to consist of a transmitted acoustic wave, a reflected wave, and an entropy wave. When the thermal‐field wavenumber is near the entropy wavenumber or twice the acoustic wavenumber, resonance‐like phenomenon occurs, resulting in large‐amplitude scattered waves.
